RADIATOR-VALVE.

Specification of Letters Itatent. Patenfd Jne 21 y Application ined september 1s, 1919. serial No. 324,504.`

radiator valves of the general type vshown in Patent No. 1,322,012, issued November 18, 1919, and has `for its particular object to simplify and cheapen kthe manufacture of such valves, as Well as to improve theirV eitectiveness of operation.

Our improved valves inthe forms shown in this and said patent above referred to are adapted for right and left hand vertical or horizontal4 connections, being in effect interchangeable or universal in character and, therefore, adaptable to `any standard form of radiator connections.

Ourv improved valve is also adaptable to viz., single pipe system and double; pipe system. yAsapplied to the'double `pipe system the inlet port of the-valve may be regulated by means of a handle having a pointer the volume of steam passingto the radiator may be controlled, `increased or diminished as may be desired. As used with a single pipe system the valve may be opened to full capacity and closed instantly merely by moving the valve controlling handle to the limits of its movement, respectively, which ashere shown is substantially 120 degrees.

Various incidental improvements have been carefully worked out in the development of our invention which in their collective effect tend to make the valve distinctly meritorious, especially as applied to radiators of the single pipe type. These features consist Vgenerally ofl ground-in `ioint construction which acts to prevent the escape vof steam around the valvexstem either as the valveis closed or opengthestufiing box is so designed'that itmay be packed under pressure; the valve seat i'sdisposed in a vertical plane and otherwise shaped to prevent the -accumulation ofy foreign matter thereon` and `thereby preventing `the proper functioning of the valve; the operableparts are essen- 'the valve casing,

tially offsimple, durable construction and of a character which will notbe ai'ected by the corroslon yof the parts or the action ofthe heat. thereon, thus Ainsuring'the normal operation ofthe valve under all' conditions.

he Vvalve is in the important particulars stated, an improvement of the typefof steam radiator valve which provides for the introduction of steam and the simultaneousffre# turn of the condensation'` through the same port, the steam entering the 'valve' through the upper portions of the port, and the condensed' moisture l'being fheavier than the steam, passing fromV the valve through the lower portion of the port. In the accompanying drawings, l f Igure 1 is a side .elevation'of the valve taken with the operating parts arranged'on a horizontal plane and showing in dotted llnes` portions oli the interior arrangement of the mechanism; 1'1" f vievsTV of the 'valve disposed in avertical plane; .i i

tion, what We claim asfneiv `and desire to secure by Letters Patent, is V- l. ,In a radiator valve, a casing compris ing a port and oppositely disposed bearing apertures arranged substantially at right angles to said port and a bearing arranged intermediate said bearing apertures substantially at right angles thereto, a pistn operable to open and close said port supported in said bearing and having guide lugs to prevent rotative movement of said piston, a valve stern rotatably supported in one of said opposite bearing apertures eccentrically connected with said piston and adapted to aotuate the valve piston to full open or'olosed position by partial rotation of said stem, and a plug in the other of said opposite bearing apertures having a Contact surface cooperating with said guide lugs.

2. In a radiator valve, a casing having a port and oppositely disposed bearing apertures arranged substantially at right angles to said port, and a bearing aperture arranged in alinement with said port, a piston to open and close said port and supported in said last named aperture, said piston having guide lugs and a cam slot, a valve stem bearing member engaging in one of said opposite bearing apertures, a valve stem supported in said bearing member and having an eccentric portion engageable in said cam slot for reciprocatingthe piston, and a plug in the other of said opposite bearing apertures and engaging the guide lugs to prevent rotation of the piston, the oppositely disposed apertures being adapted to permit the interchanging of said bearing member and valve stem and the plug.

3. In a radiator valve,"a Casing having a port and oppositely disposed bearing apertures arranged substantially at right angles to said port and a bearing aperture arranged in alineinent with said port, a piston to open and close said port and supported in said last named aperture, a hollow plug en`- gaging in one of said oppositely disposed apertures, a valve stem supported in said hollow plug and cooperating with said piston to reciprocate it, and a plug in the other of said opposite bearing apertures and cooperating with said piston to prevent the rotation thereof.

In testimony whereof We aiiix our signatures.
